A, This invention relates to improvements inv the artofmanufacturingshoes. The invenvtion'is herein illustrated in itsapplication t llCKay-sewedv shoes but in certain of its aspects it isuseful also in connection with the making of other types of shoeswherein the shank stiffener is located between inner and outer soles as,for example, in welt shoes.

.In abo-pending application filed concurrently herewith in the name ofA. W. Matthews, Serial No.V 845,822, there is disclosed a method ofmaking shoes in accordance with which ashank stifener is secured at itsforward end to both the innerand outer soles of a shoe by means of 1atwo-part fastener consisting of Y an eyelet,v which extends 7 throughtheshank stiiener and the insole,

both the inner and outer soles by the employl Y mentof onlya singleunitary fasteneror a plurality voiunitary fasteners. In accordance. withthis novel method as herein exemplified, a shank stiffener `havinggarivet-receiving hole therein is secured `to the insole of ashoeand'located in predetermined relation to the shoe,la,hole.forming tool,.such as a zdrillor a punch, isinserted in the hole in theshank stiienerand therebyy located rela# tively to the Ainsole ofthe shoe after whichytheztool is operated to form a hole in the insole yregistering with thehole in the stifener,jan outsole is1laid,,and a unitary fastener, intheform of a tubular rivet, is passedinwardly through the outsole Aandthrough the registeringholesin the shank stifener and the insole, therivet making the hole through l' which it passes-inthe outsolev and theinner end of the rivet being clenched against the inner surface of theinsole so as permanently vto secure together the shank stiffener'and theinner and outer soles. Asherein illustrated, the shank stiie'ner isprovided with two rivet-receiving holes, onelocated in its formethod.

The invention will be explained with reference to the accompanyingdrawings, in which Fig. l is a perspective view of ay McKaysewed shoe inprocess of manufacture, showing the shoe as it appears after the shankstiifener has been applied to the insole but before the outsole has beenlaid;

Fig. 2 is a longitudinal sectional view of the shoe shown in Fig. 1,illustrating the manner of forming the rivet-receiving holes in theinsole;

Fig. 3 is a longitudinal sectional view of the shoeas it appears afterthe outsole has been attached to the shoe, thisfigure illustratingparticularly the manner of inserting the rivets; v

Fig. 41 is a transverse sectional view of the shoe shown in Fig. 3, thesection being taken throughone of the shank stiifener attaching rivets;and l p' l F ig. 5 is avperspective viewof a completed shoe. made inaccordance with the present n In making a McKay-sewed shoe as hereinillustrated an insole 10 is secured to a last l2 having the usualmetallic bottom plate 14 (Fig, 2)', the insole being attached by meansof tacks 16 which are driven through holes 18 inthe bottom plate 14.Thereafter an yupper 2() is lasted over `the insole and secured to thelatter by lasting tacks 22 in the usual manner. A shank stidener 24 isattached to the insole -10 preferably after the upperhas been lastedover. The shank stiliener 24, which is preferably made of te1n peredsteel, is curvedlongitudinally to correspond to the` longitudinalcurvature of the shank portion of the bottom of the last 12 and theillustrated stiiener is also arched somewhat transversely for the pwnose of stiffening it. At each end of the ener is formed a tack hole 25and as herein shown the stiifener is provided with two rivet-receivingholes 28 vwhich were preliminarily formed in the stiiener, one in theforward Vmiddle of the stifiener. -erly located upon the insole, betweenthe lastportion thereof and the other atror near the After beingproped-over margins of the, upper as shown in Fig. l, the stiffener 24is .preliminarily'attached thereto vby driving tacks 26 through theinsole,`the points ofthe tacks engaging the metallic bottom plate 14 ofthe last and bein Rivet-receiving holes 30 are thereafter Vformed in theinsole l by meansofa suitable tool such as the illustrated drill 32(Fig.

' Y 2). The vdrill 32 is first'projected through :ner and, either beforeorfafter the outsole has been secured by `stitching fto the upper, the

shank st-iffenerissecured tovboth the inner and outer soles by means oftubular rivets, such as the tubular rivets 36 (Figs. 3 to 5) Preferably,as shovvnin Fig. 3, the rivets'employed are of the type having anentering Yend'portion'beveledl to enable the rivet to force its Waythrough stock in AWhich no hole has preliminarily` been formed toreceive the rivet.l As shown in'fFig. 3, thek bevel is formed attheroutsidel of the rivet, thus insuring that thegrivet 'will littightly Within the hole Which it forms inthe outsole and furi thermorefacilitating the entrance of the rivet into the registering holes in theshank stiff-y ener and in theinsole. Ifdesired, hovvever,-

Va rivet-receiving hole may be pre1iminarilyV ,formed in the outsolebyineans of a drill or punch inserted through the alined holes inY theinsole andshank stiener from theinside ofthe shoe; f -f "As illustrated,the rivets 36 are driven by means of theV rivet-applying device shown inFig. 3 which comprises a rivet-driving plung-V er 38,v a rivet-settinganvil 40, a'positio'ning piu 42 carried by the anvil'40, andV means suchjas springtingers k44 forholdingarivet bei neath'thepluiiger 38 inposition` to be driven. v'The positioning'pinv42, asV shown,projectscentrally through the cupped upper end of the anvil 40 and iisnormally supported in operative position-by V'means ofY alsprling 46seated Within the'anvil and-arranged to per- 'mit the pin 42 to bedisplaced downwardly by the rivet as 'the latter'isforced through theholesin the shank stiifener and-insole.

'In operating the illustratedrivet-applying `device,fa shoe ispositioned, as shown in Fig.

Thisop'eration is Are-y peated for thepurpose of driving the tWo Arivi-` ets`36, shown in Fig, 5. Thetvvorivets 36v firmly and permanently1 secure the.
